Application filed September 1, 1923. Serial No. 660,584.

To all fui/710m t may concern:

Be it known that we, IVILLIAM F. BonUM and Jol-1N II. SENIOR, citizens oit' the United States, residing in Philadelphia, Pennsylvania,'ha.ve invented certain Improvements in Camel-Back Lapping Machines, ot which the following is a specification.

One object ot our invention is to improve the construction ot Camelback 'feeders for lapping machines so that the cotton can be carried up at an acute angle without being held to the conveyer by tapes and can be carried down at an acute angle without the liability ot the cotton slipping on the conveyer.

A further object oit' the invention is to design the slats so that they will guide the material positively.

A still `further object of the invention is 20 to prevent the cotton being caught in the joints ot the conveyer.

These objects we attain in the following manner, reference being had to the accompanying drawings, in which:

25 Fig. 1 is a side view of a Camelback lap ping machine, illustrating our invention;

Fig. 2 is a sectional view on the line 2-2, Fig. 1;

Fig. 3 is a detached sectional View drawn to an enlarged scale, showing the construction ot the apron or conveyer for elevating the cotton; and

Fig. 4 is a view showing the construction of the apron, or conveyer for carrying the cotton down onto the lapping mechanism.

Referring to the drawings, 1 is a frame of a Garnett machine. 2 is the main cylinder of the machine. 3 and 4 are the delivery cylinders, which are driven in the ordinary manner. Pivoted at 5 to the frame 1 is a frame 6, carrying the endless apron, or conveyer, 7. This apron passes around a drum 9 at the lower end, which is driven from the mechanism of the Garnett machine and there is a drum 10 at the upper end of the frame 6. The apron 7 consists of a series of endless belts 11 to which are secured the slats 12 and 13, shown clearly in Fig. 3. The slats 12 are higher than the slats 13 and each slat has a beveled tace terminating at one side in a comparatively sharp edge 14, the slats which simulate teeth and which engage the cotton as it comes from the Garnett` machine. The ifaces of the slats 13 are slightly rounded, as shown. The slats are placed close together andare of such a width that they pass7 readily around the drums 9 and 10.

In the present instance, a series of endless' bands is located above the apron, or conveyer, 7 These bands pass around flanged pulleys 16 onshatts 17 and 18 and are usedas a precautionary measure to hold the cotton on the apron when the 'frame 6 is at an acute angle. These bands may be omitted without detracting from the desired results.

Pivoted to the outer end of the conveyer frame 6 is a conveyer trarne 19, on which is an endless conveyer 20, which passes around drums 21 and 22. The drum 21 is driven through gearing 23, 24 and 25 from the drum 10. The lower drum 22 is mounted on a carriage 26 having wheels 27 pivoted to rails 28 on the frame 29, having bearings for the drum 31 around which the apron 30 passes on which the batt is made up on the reciprocation of the carriage 26. The endless apron, or conveyer, carries the Inaterial onto the distributing rolls 32 on the carriage and the film of cotton is spread onto the apron 30. The apron, or conveyer, 20 consists of a series of endless belts 33 to which are attached slats 34 and 35. The slats 34 are higher than the slats 35 and have beveled faces terminating at one side in sharp edges 36, which engage the cotton and prevent it sliding over the apron, or conveyer, when the apron is at an acute angle. The slats 35 are rounded in the same manner as the slats 13 of the apron 7.

Hereto'l'ore, lapping machines were provided with a single belt, which was adapted to the two frames. The belt was made of canvas and cross bars were secured to the canvas at a considerable distance apart in order to allow the conveyer to pass around the drums. The cotton had to be held onto the conveyer by tapes. This is objectionable, as the cotton has a tendency to catch in the joints between the cross bars and the belts. The cotton also had a tendency to slide over the conveyer.

In our invention, the slats are arranged close together and the cotton is carried positively by the irst conveyer and is discharged onto the second conveyer, which carries it down. tothe foldinggnachine ,with out theuse ofl'bandsor tay'pes.A L
